Yesterday, I have created a new cluster with a fresh install of CentOS 5.3, on 
three nodes. I used luci + ricci.

I disabled the firewall and SELinux (system-config-securitylevel-tui --disabled 
--selinux=disabled -q). I know it is supposed to work with SELinux now, but 
last time I tried it, it was still problematic.

You can also try the "clean_start="1" attribute in the "<fence_daemon >" tag 
(the fenced man page explains this parameter in the "Domain startup" section, 
perhaps that's why you have a long timeout during the intialization of the 
fencing)

Did you also try your fencing methods with the "fence_manual -n " command 
(useful to validate the fence device) ?
